If an animal dies and falls into a river, and over time
sand, rock, and other material settle on top of the animal remains, <span>sedimentary rock will be most likely to form because of the layering. </span>
Umm where is the questions ?
This plant is not dangerous and can help treat cancer, this plant produces Curol, something that cannot be created in laboratory, so it will be a pleasure for me to preserve this plant it is a important plant that will save many peoples life in the future. There will be a treatment for cancer and families would stop crying after lost family that dies from cancer.
<h2>CNS </h2>
Explanation:
An example of a myelin producing cell in the CNS is oligodendrocyte
- The major function of oligodendrocytes is the formation of myelin
- Myelin acts as an insulator of axonal segments and is a prerequisite for the high velocity of nerve conduction
- Larger axons form thicker myelin
- During development, oligodendrocytes arise from precursors located in the sub-ventricular zone such as the sub-ventricular zone of the lateral ventricles for the cerebrum or the fourth ventricle for the cerebellum
- In the spinal cord, oligodendrocytes originate from the ventral regions of the neural tube and in the optic nerve they migrate into the nerve from the third ventricle
- It is the oligodendrocyte precursor cells which migrate to their destination where they then differentiate into the more mature oligodendrocytes
- The proliferation of the oligodendrocyte progenitor cells is controlled by a number of growth factors released predominantly from neurons but also from astrocytes such as platelet derived growth factor (PDGF) or fibroblast growth factor (FGF)
